Carbon Calculator

How big is my personal climate impact?

It's easy to find out. Add these into the carbon calculator:

  • Vehicle travel data (per year)
  • Air trips (per year)
  • Hydro bills
  • Gas and heating oil usage
  • Food habits (your personal choices, not your entire household)
  • Consumption and waste habits

You’ll find out how many tonnes of greenhouse gases (GHGs) you have emitted in a year.  The lower your greenhouse gas emissions, the lower your impact on our planet's climate. (See notes below the table for about what the result includes and doesn't include.).  You can also check out three sample carbon lifestyles [PDF - 1003 KB] to see which one is most like you. 

What should my goal be? 

In order to protect our communities and ecosystems, greenhouse gas emissions need to come down. In order to keep global warming to 1.5 oC, greenhouse gas emissions need to be cut in half by 2030 and reduced to net zero by 2050, according to the UN Intergovernmental Panel on Climate Change (IPCC) special report released in 2018.

How can I reduce my GHG emissions? 

Choosing renewable energy on the road at and home, using energy efficiently, and making "lighter living" choices with food and consumption can all help reduce our greenhouse gas emissions. Visit the Programs and Rebates page and the Green at Home page for incentives and tips.

Consumable Goods and Waste

Most of the GHG impact of the goods we purchase occurs before we even get the product. We are collecting waste and recycling information here to estimate your purchasing habits, which is the key factor driving GHG emissions for this category. Textiles, plastics, metals, and paper typically have the highest GHG impact.

*About Your Results

This personal carbon calculator uses a combination of different methodologies.

Climate action is required from all levels – by individuals, by businesses and by governments. Your personal result on this page only include things that you have direct control over, including how you travel, energy use in your home, your food choices, and what you buy and throw away. The personal result does not include the impact of national and provincial services, like health care and military; as well as the emissions associated with creating community infrastructure like roads and buildings, which are included in the Saanich Consumption Based Emissions Inventory (CBEI)

The Food Consumption and Consumable Goods and Waste sections use a “consumption-based” emissions approach, which includes the energy used in production, processing, transportation, and disposal. Getting to zero in this tool is not possible, as your results by default include a low-carbon baseline diet (0.96 tCO2e).

The transportation and buildings sections look only at emissions from fossil fuel or electricity end use, not at the embodied carbon emissions associated with building roads, vehicles, and building materials like concrete, wood, and bricks. If embodied emissions were included, your personal transportation and building emissions would be bigger. Emissions factors for buildings and transportation are taken from the BC Best Practices Methodology for Quantifying Greenhouse Gas Emissions.


What's a "tCO2e"?

Short for "tonnes of carbon dioxide equivalent," tCO2e is a handy way of talking about all greenhouse gas emissions (e.g. carbon dioxide, methane, and refrigerants, etc.) together in the same measurement.
